Purchased this RV motorhome in December 2021. From day 1 of this purchase, I have experienced what is being called the "creepy slide syndrome". When the motorhome is parked on in motion, the two hydraulic slides will creep (extend) out about 2-4 inches and at times have been extended as far as 6 inches. Have had more than 5 service repairs, including one national recall performed and the problem still exists. Been in contact with both Tiffin, the manufacturer and Lippert, the hydraulic system manufacturer and there continuing, in my opinion, to kick the can down the road. Currently, they are saying there is a fix but no one can actually verify that is the case. Others who own Tiffin motorhomes continue to report the same problem. I filed a compliant several months ago but never heard anything further. There needs to be a second recall on this problem so that customers do not have to worry about safety issues and also so that customers do not continue to have to continue to have service appointments, at our expense, and continue to have the same problem.

What 2022 Tiffin Allegro owners say
Most recent owner complaints, unedited.
Both hydraulic forward slide rooms creep out at will. This unit was purchased new in July 2023 and was in the shop for 3 months having issues addressed. The main issue is that these slide rooms creep/drift out on their own. The dealership says that we don't have the cylinders that were part of a recall. So they bled the existing cylinders and told us to hold the retract button for four seconds after the room slides are retracted which recharges the hydraulic system. We brought the RV home and immediately the slide rooms drifted out on their own. We are afraid to drive this RV any distance because the rooms may slide out on the highway and cause an accident. The maker of the hydraulics (Lippert) plans to replace the hydraulic pump and manifold, but based on other customers feedback...this will not fix the problem. We want to go on record that this should likely be investigated (see Tiffin/Lippert Slide Creep) on Facebook to read other's details. Lippert doesn't seem to have a solution at this point. This is a danger...not to mention a $275K investment that we are afraid to use.
Large slide will come out from wall of coach four to six inches while parked and driving. National safety problem issued by manufacturer. Repair was done, lasted five months then reoccurred. Trying to get fixed again. Out of service total of six months and counting. Dealer and manufacturer know no recourse will be taken. Filed CAP RV told not eligible due to being second owner. Problem was not disclosed prior to purchase. One year warranty did not transfer. Please help.
